A lot of the recent episodes felt like they were retreading on old ground, so this episode was fun in that there was a lot of fresh material, even if it was not mind-blowing.

(SPOILER)And holy , that had to be one big-ass wave to raise the ship high enough to crash into the statue's head and then leave it in the middle of the island. Or did the island "sink" so that the head was at sea level and then raise back up after the wrecked ship was over the island?

So does the island move or does it teleport people to it? (Really? "teleport" isn't in Firefox's dictionary?) Richard was sailing across the Atlantic when he crashed on the island, yet the Losties crashed when flying over the South Pacific. Also, Mr. Eko's brother's plane crashed on the island after taking off from somewhere in Africa. So were they teleported to the island or did the island move so that it would be in their line of travel. Is this how Jacob brings people to the island?

And lastly, if the island can physically move, does it have any boundaries? It has always been portrayed as a tropical island, but what would happen if it moved above the Tropic of Cancer or below the Tropic of Capricorn? Would the island's climate change due to the colder weather or would it be impervious to outside weather conditions? All three crashes can be placed within the Tropics, so perhaps the island's movement is confined?
